Alzheimer disease is a neurological disorder that affects the elderly, caused by abnormal protein buildup in the brain. It leads to difficulties such as financial mismanagement, disorientation, behavioral changes, and repetitive speech. The existing methods use traditional features to detect the early signs of AD with low detection accuracy. The potential features have to be identified that represent best the patterns associated with alzheimers. Feature selection using ant lion optimization resolves the issue by using complementary information from hybrid features. The proposed HybridOpt pipeling for AD diagnosis combines the high level and low level features for early stage detection The objective of this work is to select efficient features from different deep networks, such as AlexNet, Googlenet, VGG16, ResNet, Efficient, DenseNet, and traditional texture features. ant lion optimization is used to select the best feature among the deep network and traditional texture feature groups. Extensive experimentation on two highly challenging datasets called the Alzheimer's disease neuroimage dataset and KAGGLE reveals that the proposed HybridOpt pipeline achieves an accuracy of 99% and 98.1% respectively.

Adaptive Neural Network- based Fractional-order PID Control (NN-FO-PID) approach is designed for H-bridge inverter. This inverter has an LC filter to decrease the level of Total Harmonic Distortion (THD) that can affect the efficiency of the system. In addition, the reduction of THD and stability insurance of the filter are challenging performances. To fulfill this function, a fractional order proportional integrated derivative (FO-PID) controller is developed for the inverter. A few merits of the Fractional-Order notion as a useful technique include reduced sensitivity to noise and parametric fluctuation;however, for a wider range of disturbances, such as noise, this approach shows an unsuitable practical application based on its fixed gain values. Moreover, having parameters uncertainties including parametric variations, load uncertainty, supply voltage variation uplifts this challenging condition severely, and the parameters need to be adjusted once more for more dependable operations. As a result, the control parameters must be optimized once more to provide ideal operations. Here, an adaptive mechanism is proposed based on neural network structure to optimize the gains of the FO-PID controller for better performances. In real applications, this approach has some benefits, since it uses the Black-box technique, which does not necessitate a precise mathematical model of the system, resulting in a reduced computational burden, simple implementation, and reduced dependence on the model's states. Even under extremely difficult circumstances, the artificial neural network structure effectively optimizes the FO-PID gains in real-time. This benefit can reduce the amount of THD-level for the inverter, properly. Additionally, to have a proper response in the first step condition, and trying to reduce the level of dangerous conditions, based on benefits of the ant lion optimization method, it is considered to select the initial values of the FO-PID controller gains.

Accurately predicting the height of the water-conducting fracture zone (WCFZ) on the coal seam roof is of great significance for ensuring the safe and efficient mining of coal seams at the mining face. To enhance the prediction accuracy of the WCFZ height, a multi-factor comprehensive analysis based on measured data from several mines in the Huainan Mining Area and Huaibei Mining Area has been conducted. A prediction index system for the height of WCFZ was established, incorporating factors such as coal seam roof type, mining method, mining depth, coal seam inclination, mining thickness, length of the working face slope, and the presence of faults in the working face. The primary component of their prediction model is the Support Vector Regression (SVR) model. Factor analysis (FA) was utilized to optimize the original data structure, and the ant lion optimization (ALO) algorithm was used to optimize the penalty factor "C" and the kernel function parameter "g" of the SVR model. Consequently, a prediction model for the WCFZ height was established based on FA-ALO-SVR. Subsequently, the predictive performance of the model was tested using new samples, and a comprehensive evaluation was conducted from three perspectives: prediction accuracy, prediction ability, and generalization ability. Five indicators, namely, mean absolute error (MAE), root mean square error (RMSE), mean relative error (MRE), Willmott's index of agreement (WIA), and Theil inequality coefficient (TIC), were used for the comparison with the traditional SVR model, the FA-SVR model, the ALO-SVR model and gray wolf optimization (GWO)-SVR model. The results indicated that the model achieved the lowest values for MAE, RMSE, MRE, and TIC, as well as the highest WIA value. Specifically, these values were 3.7857, 4.5393, 7.9066%, 0.1099, and 0.9370 respectively. This performance demonstrates a strong predictive capability of the model. Finally, the model was utilized to predict the height of WCFZ at the 3220 w

This manuscript presents an innovative control strategy for the Hybrid Excitation Permanent Magnet Synchronous Motor (HEPMSM) designed for electric vehicle (EV) applications. The strategy combines Maximum Torque Point Tracking (MTPT) and Maximum Torque Per Ampere (MTPA) techniques to track the ideal torque-speed profile, ensuring maximum torque at low speeds for starting and climbing, and high power at higher speeds for cruising. A novel unidirectional excitation current method is proposed to replace traditional bidirectional field current control, eliminating the risk of permanent magnet demagnetization, reducing copper losses, and increasing efficiency. This approach extends the constant power (CP) region by a 4.2:1 ratio. The manuscript also introduces a detailed mathematical model, considering both iron core losses and their impact on the EV profile. Additionally, the Multi-Objective ant lion Optimizer (MOALO) algorithm is used in two stages: first to optimize the hybridization ratio (HR) and base speed (Nb), and second to analyze the effect of varying the hybridization ratio while maintaining constrained output power. The proposed strategy is validated through MATLAB simulations, demonstrating its effectiveness in achieving high acceleration, efficiency, and reliability for EV applications.

The amount of data generated is increasing day by day due to the development in remote sensors, and thus it needs concern to increase the accuracy in the classification of the big data. Many classification methods are in practice;however, they limit due to many reasons like its nature for data loss, time complexity, efficiency and accuracy. This paper proposes an effective and optimal data classification approach using the proposed ant Cat Swarm optimization-enabled Deep Recurrent Neural Network (ACSO-enabled Deep RNN) by Map Reduce framework, which is the incorporation of ant lion optimization approach and the Cat Swarm optimization technique. To process feature selection and big data classification, Map Reduce framework is used. The feature selection is performed using Pearson correlation-based Black hole entropy fuzzy clustering. The classification in reducer part is performed using Deep RNN that is trained using a developed ACSO scheme. It classifies the big data based on the reduced dimension features to produce a satisfactory result. The proposed ACSO-based Deep RNN showed improved results with maximal specificity of 0.884, highest accuracy of 0.893, maximal sensitivity of 0.900 and the maximum threat score of 0.827 based on the Cleveland dataset.

Inverse modeling of thermal decomposition of flame-retardant flexible PVC with model-free coupled with model-fitting method

The thermal decomposition model of flame-retardant flexible PVC is essential for relevant waste management and predicting its fire behavior. In this work, thermal decomposition kinetics of this material was investigated via thermogravimetric analysis in non-isothermal conditions. The kinetic analysis was performed using model-free (including Kissinger, Friedman, and advanced Vyazovkin methods) coupled with model-fitting method (ant lion optimization algorithm, ALO). The kinetic parameters obtained from model-free method provide guides for initial guess and search range for ALO. Two different decomposition models are developed and the validations show that second two-step parallel model could better predict experimental data and explain the decomposition process. The performance of ALO is compared with Shuffled Complex (SCE) Evolution algorithm. The results show that the ALO shows better performance because all solutions from SCE are trapped in local minima. In this way, the ALO could be used as an alternate optimization tool for inverse modeling.

Cuckoo search algorithm (CSA) and ant lion optimization (ALO) algorithm have been explored in this work to optimize the gains of Fractional Order Fuzzy Sliding Mode Proportional Derivative Controller (FOFSMCPD). The controller has been applied to control a highly nonlinear and coupled multi-input multi-output system, i. e. a two link planar rigid robotic manipulator. In present case, the optimization problem is in the form of minimization of weighted summation of integral of absolute error and chattering, for the efficient control of robotic manipulator. On the basis of conducted investigations, it is inferred that FOFSMCPD, tuned by CSA for trajectory tracking shows much better performance than the onetuned by ALO algorithm, for set point tracking, disturbance rejection and noise suppression.
